问题
I am using spring WebSocket WebSocketClient to connect with GDAX server.
It is working fine with the Live environment, but the same code is not working with the sandbox environment.
Here is my code to connect to the server:
public class Test {
public static void main(String[] args) throws InterruptedException {
String socketURL = "wss://ws-feed.gdax.com"; //Live URL
//String socketURL = "wss://ws-feed-public.sandbox.gdax.com"; //sanbox URL, code will not work if you use sandvox URL
WebSocketClient client = new StandardWebSocketClient();
WebSocketConnectionManager connectionManager = new WebSocketConnectionManager(client, new MySocketHandler(), socketURL);
connectionManager.start();
Thread.sleep(1000000);
}
}
class MySocketHandler extends TextWebSocketHandler {
Logger LOG = LoggerFactory.getLogger(MySocketHandler.class);
@Override
public void handleTextMessage(WebSocketSession session, TextMessage message) {
LOG.info("Message Received [" + message.getPayload() + "]");
}
@Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
LOG.info("Connected");
String payload = "{\"type\": \"subscribe\",\"channels\":[{\"name\": \"heartbeat\",\"product_ids\": [\"BTC-USD\"]}]}";
LOG.info("Sending [" + payload + "]");
session.sendMessage(new TextMessage(payload));
}
@Override
public void handleTransportError(WebSocketSession session, Throwable exception) {
LOG.error("Transport Error", exception);
}
@Override
public void afterConnectionClosed(WebSocketSession session, CloseStatus status){
LOG.info("Connection Closed [" + status.getReason() + "]");
}
}
Above code is working fine with the Live URL and output is:
15:52:10.940 [main] INFO org.springframework.web.socket.client.WebSocketConnectionManager - Starting WebSocketConnectionManager

But when I run same code with the sandbox URL, It gives error:
